FAQ & Knowledge
Frequently Asked Questions: Borrowing Power
Key mortgage guidelines, statutory fees, and investment benchmarks at a glance:
?How much can I borrow on a UK mortgage based on my salary??
High-street lenders typically lend between 4.0x and 4.5x your gross annual household income (or up to 5.0x to 5.5x for high earners and specific professional roles).
?How do credit cards, car finance, and student loans affect borrowing power??
Lenders deduct monthly contractual debt commitments (credit cards, PCP car finance, personal loans) from your net disposable income, directly reducing your maximum borrowing ceiling.
?Can self-employed borrowers pass mortgage affordability checks??
Yes, self-employed applicants typically need to provide 2 years of SA302 tax calculations and Tax Year Overviews (or certified accounts) to verify average net profit.
?How do lenders stress-test mortgage affordability??
Under FCA guidelines, lenders verify that you could continue to afford monthly repayments if interest rates were to rise by 2% to 3% above the product rate.
?What deposit percentage do I need to buy a home in the UK??
The minimum deposit for a residential purchase is 5% (95% LTV). However, saving a 10% or 15% deposit unlocks substantially cheaper interest rate tiers.
?What additional buying costs must I budget for beyond the deposit??
Budget roughly £1,500 to £2,500 for legal conveyancing fees, £400 to £900 for a RICS home survey, mortgage valuation fees, and any applicable Stamp Duty.
